我是 android 开发和 stackoverflow 的新手,所以请放轻松。;)

我创建了一个包含多个 TextView 的 ViewGroup。特别是有一个 switch case,其中 case 常量是我的 java 对象中定义的整数。然后,我将 case 语句设置为我认为是 String 值的值。最后我使用 setText() 方法将 TextView 对象设置为这个字符串。我遇到的问题是,实际上返回到视图的是与案例相关联的整数,而不是文本值。这让我相信我传递给 TextView 的是一个 int 但我不知道如何或在哪里可以纠正这个问题。

任何帮助将不胜感激。

ViewGroup 代码在这里:

public View getView (int position, View convertView, ViewGroup parent)
    {
        ViewGroup listItem;
        if (convertView == null) {
            listItem = (ViewGroup) getLayoutInflator().inflate(R.layout.list_item, null);
        }
        else {
            listItem = (ViewGroup) convertView;
        }
        MovieInfo movieInfo = list.get(position);
        TextView movietitleText = (TextView) listItem.findViewById(R.id.movietitle_text);
        TextView directorText = (TextView) listItem.findViewById(R.id.director_text);
        TextView producerText = (TextView) listItem.findViewById(R.id.producer_text);
        TextView releaseyearText = (TextView) listItem.findViewById(R.id.releaseyear_text);
        TextView genreText = (TextView) listItem.findViewById(R.id.genre_text);

        movietitleText.setText(movieInfo.getMovietitle());
        producerText.setText(movieInfo.getProducer());
        directorText.setText(movieInfo.getDirector());
        releaseyearText.setText(movieInfo.getReleaseyear());

        String genreName;
        Resources resources = context.getResources();
        switch (movieInfo.getGenre()) {
        case MovieInfo.GENRE_ACTION:
            genreName = resources.getString(R.string.action_label);
            break;
        case MovieInfo.GENRE_COMEDY:
            genreName = resources.getString(R.string.comedy_label);
            break;
        case MovieInfo.GENRE_DRAMA:
            genreName = resources.getString(R.string.drama_label);
            break;
        case MovieInfo.GENRE_FAMILY:
            genreName = resources.getString(R.string.family_label);
            break;
        case MovieInfo.GENRE_HORROR:
            genreName = resources.getString(R.string.horror_label);
            break;
        case MovieInfo.GENRE_ROMANCE:
            genreName = resources.getString(R.string.romance_label);
            break;
        default:
        case MovieInfo.GENRE_UNKNOWN:
            genreName = resources.getString(R.string.unknown_label);
            break;
        }
        genreText.setText(genreName);
        return listItem;
    }

case 常量在我的 java 对象中定义:

public static final int GENRE_UNKNOWN  = 0;
public static final int GENRE_ACTION   = 1;
public static final int GENRE_COMEDY   = 2;
public static final int GENRE_DRAMA    = 3;
public static final int GENRE_FAMILY   = 4;
public static final int GENRE_HORROR   = 5;
public static final int GENRE_ROMANCE  = 6;

private String movietitle;
private String director;
private String producer;
private String releaseyear;
private int genre;

选中复选框时设置流派的操作位于此处的主要活动中:

if (actionCheckBox.isChecked()) movieInfo.setGenre(MovieInfo.GENRE_ACTION);
if (comedyCheckBox.isChecked()) movieInfo.setGenre(MovieInfo.GENRE_COMEDY);
if (dramaCheckBox.isChecked()) movieInfo.setGenre(MovieInfo.GENRE_DRAMA);
if (familyCheckBox.isChecked()) movieInfo.setGenre(MovieInfo.GENRE_FAMILY);
if (horrorCheckBox.isChecked()) movieInfo.setGenre(MovieInfo.GENRE_HORROR);
if (romanceCheckBox.isChecked()) movieInfo.setGenre(MovieInfo.GENRE_ROMANCE);

Strings.xml 的一部分在这里:

<string name="movietitle_label">Movie Title</string> 
<string name="director_label">Director</string> 
<string name="producer_label">Producer</string> 
<string name="releaseyear_label">Release Year</string> 
<string name="genre_label">Genre</string> 
<string name="action_label">Action</string> 
<string name="comedy_label">Comedy</string> 
<string name="drama_label">Drama</string> 
<string name="family_label">Family</string> 
<string name="horror_label">Horror</string> 
<string name="romance_label">Romance</string> 
<string name="unknown_label">Unknown</string> 
<string name="ok_label">OK</string> 
<string name="clear_label">Clear</string> 
<string name="showdatabase_label">Show Database</string> 
<string name="id_label">ID</string> 
<string name="select">Select Year</string> 

谢谢你的帮助!

我没有看到您的代码有任何问题。这里有几件事可以尝试(也许您只需要重新编译并重新运行它?):

尝试使用资源 id 而不是字符串(即 R.string.unknown_label 等)调用 setText:https ://developer.android.com/reference/android/widget/TextView.html#setText%28int%29

在调用 setText 之前尝试记录genreName 的值:

Log.d("MovieGenre", "genreName=" + genreName);
